ButtonTheme class Null safety

Used with ButtonThemeData to configure the color and geometry of buttons.

This class is obsolete.

Please use one or more of the new buttons and their themes instead: TextButton and TextButtonTheme, ElevatedButton and ElevatedButtonTheme, OutlinedButton and OutlinedButtonTheme. The original classes have been deprecated, please migrate code that uses them. There's a detailed migration guide for the new button and button theme classes in flutter.dev/go/material-button-migration-guide.

A button theme can be specified as part of the overall Material theme using ThemeData.buttonTheme. The Material theme's button theme data can be overridden with ButtonTheme.

The actual appearance of buttons depends on the button theme, the button's enabled state, its elevation (if any), and the overall Theme.
